of the United States, residin tain new and useful Improvements in Elecfollowing 'is, a specification. j

My invention relates to an improvement in electrictransmission of energy Its object is, toproduce an arrangement for transmittinglines whereby true reversalsmay be transm1tted=from one terminal. station to the.

other terminal station,-without necessitating the changing of the devices placed at the station.

It it also object to simultaneously telegraphand telephone over the same line.

In the drawings, I have illustrated in Figure 1 myarrangement as applied to. a.

composite, 1ine,'tha t is, a line: inductively connecting two stations with each other, the two wires of the line beingtwisted around each other, so as toproduce a greater iIi-' ductive eiiect. In Fig; .2, I have illustrated my invention asbeingapplied to.a metallicline grounded at each terminal station; but it is obvious that instead of aground a return wire may be employed, without de-i partin from the scope of my invention.

In grammatic views of a transmitting line provided each with two terminal stations embodying my invention; In, Fig. 1, A is the composite line comprising the conductors A at-= the station S with the source of current number.

"lhe polarized f; isconnected in series as to theline 'andl'grdund at both stations and I have designated the "from that of the first named relay, or at t hefdrawing's, Figsyl and 2 are dia microphonic transmitter J ,'the primagly of So far the arrangement of both stations is alike, but whereas in station S the battery B. connects with the positive pole as to the line and the battery C connects wlth the positive pole as to the ground, the order atstation S is reversed; the battery Q connects with. the positive pole as to the hne. and the battery B with the positivepole as to the ground. Whereas, therefore-,- the current from the source of greater electro-motlve force will flow at thestatioii r the-'unfe a transmitting key. Dfadapted to 6. B 1

-merals'1 and 2, so asto clearly define the connectionof said relay as to the line and 75. ground and it will be seen from these drawings that whereas at station S the terminal r of the relay E is connected to the line and the terminal 2 tothc ground, the connection of the relay E at the'stationS' is op osite 30 this st'atio'n'the 'terminalof the relay 2 is connected to the line and the terminal of the relay 1 is connected to the groundll InFig. 2, similar letters designate similar parts, but the line consisting of only one conductor'is designated as A. In th1s line are also inserted, at each station, telephonic transmitting and'receiving devices; the transmitting device embracing the battery. K, the

the inductorium I, the secondary"; of whi'ch'is connected intheline. In the; line is also connected at each stationjthe here. phonic receiver N; In thisfigure, the relays. E and E are also provided with a shunt consisting of the condensers G of comparative small capacity and the primary P of an inductorium, the secondary Z of which is closed around itself.. The shunt can be closed through the switch H. The receiver N is inshunt with the primary P and this shunt can be opened and closed through a switch, as desired.

I will describe the o eration of the arv 3 beginning in. the direction of the unfeathered arrow. When the operator at station S. de sires to transmit telegraphic messages, he closes his key is accordance with the characters to baa-transmitted. As soon as his key m is closed, the source 13 is shunted and through this shunting-an impulse will flow over the line invthe direction of the feathered arrow. This impulse is due to the dischargthe potentials of thesources of current in theline being zero, the potentials of the condensers will also fall to zero, but as soon as the. kelyiis open, the potential of the bat-j teries yvi be plus Gand, therefore; an iming the condensers. Should the operator. at stationfi' depress his key, then a impulse will flow over the line similar to t e impulse when the operator at stationyS depressed his hey, that is, in the direction of the feathcred arrow, but' as soon as the operator releaseshis key, an impulse will flow inthe direction of the unfeathered arrow. Through the insertion of the condensers all impulses will be, limited to a like duration. Through this, reversed fiow-of'impulses, the tongue of the relays E and EWvill be operated on and through this'operation a lo cal circuit will be 1118118 01 broken. I have' found that over such lines telephonic impulses can be transmittedsiinultaneously with the transmitting of telegraphic impulses, provided that the telegraphic relays are built in a manner, so that impulses traveling through a condenser could afiect them in the same manner as the; usual olarized relaysare afiected by the flow '0 a voltai'c current. Such relays require for their electromagnets a large amount of ampere turns and these electromagnetsQthere'fore, otter to the telephonic impulses a great, resistance and impedance. After careful experiment was, resistance, coils and' condensers, I have jfoiindthat, if condensers 'offvery small capacity are as so necteid in shunt as to the coils of the relay, thejtelephonic impulses will travel through these condensers, out the'tcleph'onic impulses will' fioiy in the greater part.thro ugh the coils"ofthe relay.' At the first glance, it wo seinthat both the telephonic and hpjmpuls es. would travel through theco ers'rather than through the coils of th re y for'th'e reason that both of these imphlssiaiejtlue'to the charging and dis.- g ig oijthecondensers I! and 1n reality hese inipuflses"'would seek the cbndensing Silltflitiiil thieir eni'irctyg were it n'ottior the se son "t ,the condensing shunt is of such sminll' c'ap'aity',that only a vcry small part on of' the charge o/I' the largo condensers can ing ofthe condenser F, for the reason that pulse will fiow in the same direction charg pass through the same, and the larger part has, therefore, to go through; the coils. Again, the telephonic impulses are so feeble, that they can, in their entirety; pass through condensers even of suchsniall ca- 7 pacity as is employed in the shunt. In the drawing, I have'illustrated this shunt as to consist of three condensers inseries, each condenser having a capacity of one-fourth of a M. F. Thewhole shunt, therefore, has a capacity of one fourth divided by three? which equals one-twelfth of F Braetice has shown that with the intervention of the inductorium P, the received sounds are more distinct that if such inductorium 6 would not be present; It seems that the I impulses reacting from the primary on the secondary give more satisfaction than When I a simple non-inductive" resistanceffis em-'" ployed for this inductorium.
